Since you are getting a TT, don't skimp on the WD hitch...
I have 1 suggestion to use and I am talking from buying, using, and swear by it. .
The Hensley Hitch...
www.hensleymfg.com ... .
go to the website and get the free video... . Trust me if you want to have NO sway acocciated with TT's, get the hensley and you will have a TT that tows like a 5th wheel.
This hitch does not use friction sliders for antisway... . but uses an ingenious pivoting system that when you are straight, things like wind and such do not make the pivot work... . Only by the truck itself, turning a bit, does it make an angle for following the turn... .
Whn you visit the site and see the price you may balk... . but think about it, one bad gust or sway at speed will wreck both truck and trailer... . So I figured 10 % of the cost of the trailer being the hitch is well worth it.
